Blind deblurring of spiral CT images

The temporal bone is a complex paired set of structures at the skull base which contains the organ of hearing among others. Treatment of severe to profound, bilateral hearing loss often employs a multi-electrode cochlear implant inserted into the inner ear part of the temporal bone. CT scanners cannot resolve many important temporal bone details, especially bony anatomy. We improve the high-contrast spatial resolution of CT with blind deblurring of CT slices and test the improvement using a phantom test object. The improvement in visible detail or clinical scans is apparent subjectively and approaches 33% quantitatively.
